ELECTRIC GENERATOR.

SPECIFICATION forming part of Letters Patent No. 695,524, dated March`18, 1962. 1

Application filed August 29,1901. Serial No. 7Ii756. (No model.) i

To all u'wm, t muy concern:

Be it known that I, ENOCH CLAUD WOOD- ELL, a citizen of ,the UnitedStates, residing at Highpoint, in the county of Guilford and State ofNorth Carolina, have invented certain new and useful ImprovementsvinElectrical Generators; and I do declare the following t be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains toniake and usethesame.

The invention relates to electrical generators.

The object of the invention is to operate a dynamo-machine by suctionorvacuum created by the passage of a current of warm or WVith thisandother objects in view the invention consists of certain novel featuresof construction, combination, and arrangement of parts, which will behereinafter more fully described, and particularly pointed out in theappended claims. y

In the accompanying drawing the figure is a view illustrating, partly insection and in conventional f'orm, my invention.

Referring to the drawing, 1 denotes an uptake or tluehavinga horizontalcommunicat- ,ing branch 2.

3 denotes a heater placed within the horizontal branch 2 of the Hue,preferably an electrical heater connected up with a smitable number ofbatteries 4.

5 denotes an inclined deflector arranged in the horizontal branch 2 toone side of thev electric heater, so as to deflect the heat directlyinto the vertical part l of the vflue, thus drawing through the open endof the branch 2 currents of air, which are entrained with the heated airfrom the electrical heater and pass up out of the upper end of the flueor uptake 1.

6 denotes a dynamo-electric machine, to

the armature-shaft 7 of which is fixed a fan or propeller whee18, whichprojects into the open en'd of the horizontal branch 2 of the flue.

In operation as the air is drawn through the open end of the horizontalbranch 2 by the heated air passing upwardly through the uptakel the fanor propeller wheel will be rapidly rotated, thus rotating thearmatureshaft and generating electricity in the usual manner.

From the foregoing description, taken in' connection with theaccompanying drawing, the construction, mode of operation, and advvantages of the invention will be readily understood without requiring amore extended explanation.

While I have shown an electric heater for 6o creating a current of air,I would have it distinctly understood that I do not wish to limit myselfto this form of heater, as it is perfectly obvious that any other formof heater may be used and the same result produced. Having thusdescribed my invention, what v I claim, and desire to secure by LettersPatent, is- ,c L

`1. A dynamo-electric machine, in combination with a flue, aheaterforcausinga suction 7o in said flue, and a fan or propeller connected tothe armature-shaft of the dynamo-machine and extended within the forceofthe suction, substantially as set forth. y 2. The combination witha`verticaltluehaving a horizon talbranch communicating therewith andopen to the atmosphere, a heater arranged within the horizontal branchof the 'u'e immediately below the uptake, a detlector for deflecting theheat directly into the up- 8o take, a dynamo-electric machine, and a fanor propeller fixed to the shaft of the arma# ,ture and projecting withinthe open end of the horizontal branch and rotated by the air passinginto said branch and entrained by the heat from the heater,substantially I,as set forth.

3. A dynamo-electric machine, in combination with a flue, a heater forproducing a current of air in said flue, and a fan or propeller 9ooperatively connected to said dynamo-eletcric machine and actuated bythe air-current, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribingwitnesses.
